We're rehasing a debate that's been pretty thoroughly covered here, but I'm (happily) unemployed at the moment, so what the heck. You're equivocating pretty nastily there. "A ton" and "prodigious" can mean a lot of things. He had good power potential and he had some good home run seasons, but neither the projections nor the previous seasons pointed to 66, 63, 50, 64. He didn't enter his prime and start doing it, he was past where his prime "should" have started. Statistical prime is in the 25-29 range, and he showed a sort-of glimpse at 27 and turned it on at 29. His pre-29 high BA, OBP and SLG (in different seasons) were 300, 339, 564. His post-29 high, when he already should have established the type of player he was, were 328, 437, 737. Those were quantum leaps to a completely new level of performance quite a bit past what he had ever shown before. Up until his age-29 season, he was following a perfectly normal development curve for a high-K power prospect, then suddenly and without warning he jumped into the stratosphere. That's a very clear profile of a potential PED user, and seeing as it happened concurrently with a lot of admitted PED use, I think the profile is very clear. Can anyone point to any similar career paths outside of the recent era? At age 28, his most comparable players from baseball-reference.com were Dale Murphy, Reggie Jackson, Jeff Burroughs, Tom Brunansky, Jimmy Wynn, Roger Maris, Jack Clark, Dave Winfield, Bobby Bonds, and Jesse Barfield. The only player on that list to take a major step forward was Jack Clark, who did it beginning at age 31 and nowhere near to the level of what Sosa did.
